DETAILED DESCRIPTION

This following description proceeds with reference to the accompanying figures, which are filed herewith and form part of this application. Disclosed herein are embodiments of flexible fluid reservoirs that may include a front sheet and a rear sheet that may be fully or partially sealed around their mutual perimeters to form a bladder. The reservoirs may include at least a first fluid port in an upper portion of the reservoir and at least a second fluid port in the upper or a lower portion of the reservoir. The first fluid port may be relatively larger than the second port and can be used to fill the reservoir with fluid and/or solids (e.g., ice), dispense the contents from the reservoir, and/or to clean the reservoir by inserting objects into the reservoir. The second port can be used as an exit port, such as by coupling the exit port to a tube and/or outlet valve.

While the front and rear walls of a bladder-type reservoir are normally flexible to allow the bladder to expand and contract as the fluid volume changes, the reservoirs disclosed herein can include rigid structural portions in combination with flexible bladder wall portions to provide increased stiffness in desired portions of the reservoirs. Some disclosed reservoirs may include a rigid spout assembly that may be coupled to all or a portion of a top seam of the bladder and may include at least the first fluid port. The spout assemblies disclosed herein may also include a removable and resealable cap, such as a threaded screw-type cap, to open and close the first fluid port. Such rigid spout assemblies can provide a gripping portion to hold and manipulate the reservoir, can provide an enlarged surface area that connects to the top seam of the bladder to distribute forces applied between the bladder and the spout portion, can provide a desired size, shape and orientation of at least the first fluid port, can help counteract torque applied while twisting the cap, and/or can help shape and/or flatten the bladder.

Some embodiments of the disclosed reservoirs may include a generally oval-shaped spout assembly that may be coupled to a top seam of a bladder, for example by welding. The spout assembly may include an outer frame, which may be welded to the top seam or top bladder opening, and a sealable insert. The sealable insert may be insertable and removable from the outer frame and/or may include lockable cam leavers configured to seal the insert within the outer frame. The sealable insert may include one or both of a first fluid port and a second fluid port.

Additionally and/or alternatively, some embodiments may include a generally oval-shaped spout assembly having an outer frame and an insert. The insert may be removably locked and/or sealed within the outer frame via a tightening collar disposed around a first fluid port. The tightening collar may include at least two wing members disposed on opposing sides of the tightening collar. The outer frame may include at least two engagement members, such as slots, disposed on opposing sides of the outer frame configured to retain the at least two wing members. A second fluid port may be removably disposed within the first fluid port. A drink tube disposed within the second fluid port may act as a tether for a cap of the first fluid port.

Additionally and/or alternatively, some embodiments may include a spout assembly including an outer frame and an insert wherein the outer frame may be semi-flexible and/or tensionable. The outer frame may be anchored to a top bladder seam (e.g., via welding, bonding, and/or belt loops disposed along top seam of the bladder). The outer frame may be disposed within the belt loops and may be anchored to the top bladder seam via a cam lever. The cam lever may be tightened and/or loosened to secure or remove the insert. The insert may include at least a first fluid port.

Additionally and/or alternatively, some embodiments may include a spout assembly including at least a first fluid port and/or one or more handle anchors welded within the bladder top seam.

Additionally and/or alternatively, some embodiments may include a spout assembly that may be welded to a center of a bladder sheet. The bladder sheet may then be folded and sealed along perimeter. The spout assembly may include one or more foldable wings that may also be sealed to the bladder and/or may fold with the bladder and serve as grasping features. A foldable wing may include a hang loop mount and/or a connecting feature for a long handle.

Additionally and/or alternatively, some embodiments can include a flexible bladder, a strut member and a spout assembly including a cap for sealing a first fluid port. The first fluid port may include an internally threaded spout. In some embodiments, the cap can include one or more grip features configured to assist with twisting the cap to seal the first fluid port or to remove the cap from the first fluid port. The cap can include a second fluid port disposed within it. The second fluid port can include an outlet valve, such as a bite-valve that can be operated by biting on the valve. The cap may include a base and the second fluid port can extend from the base such that the outlet valve opening extends towards or beyond a top portion of the bladder. In some embodiments, the cap and/or outlet valve can include an open position, in which fluid can flow from the bladder through the outlet valve, and an off position, in which fluid is blocked from flowing out of the outlet valve.

In some embodiments, the strut member can at least partially or completely be disposed around the cap and/or the first fluid port. In some embodiments, the strut member can be welded or bonded to the bladder. Alternatively, the strut member can be removably attached to the bladder. For example, the upper portion and the lower portion can be removably attached to the bladder via a snap fit mechanism.

In some embodiments, all or a portion of the strut member can include an angle of curvature that can approximate the curvature of the bladder when filled with fluid. Alternatively, the strut member can be substantially planar. The strut member can have a width that is greatest at the top portion and a width that is narrowest at the middle portion.

In some embodiments, the spout assembly and/or the strut member may be disposed on a first side of the bladder. In some embodiments, the strut member can be disposed on the first side, top seam and the second side of the bladder. Additionally and/or alternatively, the spout assembly can be disposed on the top seam of the bladder.

In some embodiments, the bladder can include a first sheet, a second sheet, a top seam and/or a bottom gusset. The top seam can be substantially straight. The bottom gusset can include a gusset piece attached by welding, bonding or other known attachment means to the first sheet and the second sheet. The gusset piece can include a rectangular, triangle, rhombus and/or other gusset shape. In some embodiments, the reservoir can include a top gusset and/or a bottom gusset. The gusset can include a gusset piece having central fold such that excess material of the gusset piece folds inwards towards the center of the bladder. In some embodiments, the bladder can include a bottom opening and/or a top opening that can be removably sealed via a clip or a slider or other removably sealing means.

In some embodiments, the bladder can include a first sheet and a second sheet. The second sheet can include a substantially planar configuration. The first sheet can be larger than the second sheet. For example, the first sheet can include a three dimensional shape such that the spout assembly and/or strut member are elevated above the second sheet. The first sheet can be molded to include the three dimensional shape and/or the first sheet can be attached to the strut member, wherein the strut member is molded into a non-planar shape. The bladder can include a first depth at a top portion and a second depth at a bottom portion. The first depth can be greater than the second depth.

FIGS. 1-13 illustrate an exemplary reservoir 130 that includes a flexible bladder 132 and a spout assembly 134 including an insert 136. The bladder 132 can have a flexible front sheet 131 and a flexible rear sheet 133. The front and rear sheets 131, 133 can be joined at their lateral edges to form an internal region for storing fluid. The spout assembly 134 can be upwardly facing and can be coupled to the upper edge portions of the front and rear sheets 131, 133.

The insert 136 may have a generally oval or almond shape and a rigid wall 138 or surface surrounding the perimeter of the insert 136. The insert 136 may be coupled to a top seam of the bladder 132 via welding, adhesive or any other sealing means along the wall 138. The insert 136 may include a first fluid port 140 that may be centrally located in the insert 136. Two or more handles 142 may be disposed on either side of the first fluid port 140. The handles 142 may be configured for gripping by user hands and/or as an anchoring point for a tether 144 attached to a cap 146 for the first fluid port 140.

A second fluid port 148 may be disposed on a lower portion of the bladder 132 and may be coupled to a tube 150 and an outlet valve 152, such as a bite-valve that can be operated by biting on the valve. The reservoir 130 may further include a control valve 154 for controlling flow of fluid in the tube 150, disposed between the second fluid port 148 and the outlet valve 152. The second fluid port 148 may be disposed with an opening facing upwards. The insert 136 may further include a clasping member 156 configured to retain or releasably retain a portion of the tube 150 adjacent the control valve 154.

The bladder 132 can also include a welded inner perimeter 158 extending around the second fluid port 148 and/or welds 160 coupling the front and rear walls at locations in the bladder 132 that are spaced from the first and second fluid ports 140, 148 and the outer perimeter of the bladder 132. The welds 160 can act as baffles and can help maintain a flatter shape of the bladder 132 when filled. A bottom bladder seam may include a bottom handle 162.

FIG. 14 illustrates an exemplary reservoir 170 that includes a flexible bladder 172 and a spout assembly including a base member 176. The base member 176 may include one or more wing members.

The bladder 172 can comprise a single sheet of flexible material that is folded to form a fold at the top end of the bladder. The front wall and rear wall of the bladder 172 extend downward from the fold at the top end of the bladder. The side edges and lower edges of the two walls can be welded together to form a sealed perimeter. This construction of the bladder 172 can allow the spout assembly to be secured to the single bladder sheet before the sheet is folded. For example, with the bladder sheet lying flat, the base member 176, a connecting member for a handle and a second fluid port can be secured to a common side of the sheet, and then the sheet can be folded at the upper edge to place the base member 176 at the upper edge and the connecting member for a handle and the second fluid port on opposing sides on the bottom portion of the bladder 172. The second fluid port may be disposed on a lower portion of the bladder 172 and may be coupled to a tube and an outlet valve, such as a bite-valve that can be operated by biting on the valve.

In other embodiments, a single bladder sheet can be folded about the bottom end of the bladder 172 or about one of the lateral edges of the bladder 172. Alternatively, the bladder 172 can be formed from two separate sheets welded together around their entire perimeter. The bladder 172 can also include a welded inner perimeter extending around the second fluid port and/or welds coupling the front and rear walls at locations in the bladder 172 that are spaced from the first and second fluid ports and the outer perimeter of the bladder 172. The welds can act as baffles and can help maintain a flatter shape of the bladder 172 when filled. The reservoir 170 can include a handle 186.

The handle 186 can provide a gripping location to hold and manipulate the reservoir 170. For example, a user can hold the handle 186 with one hand to provide counter-torque while turning a cap with the other hand to open or close the first fluid port. A user can also hold the handle 186 to fill or clean the reservoir 170, or use the handle 186 to hang the reservoir 170.

In some embodiments, the handle 186 is detachable and re-attachable. In some embodiments, the reservoir 130 can have a handle similar to handle 186.

Any flexible and waterproof material can be used for the bladder, such as various polymeric materials. The rigid components (e.g., spout portion, back plate, optionally the connector, strut member) can comprise any sufficiently rigid material, such as polymers, metals, etc. The disclosed reservoirs can have any dimensions and fluid capacities. The relative dimensions provided as examples herein are not limiting.
